Dam Vezins

This stopping is with multiple vaults, with reinforced concrete buttresses makes 36 meters in height and 276 m length. It is eight times more powerful than that of Rock-which-Drinks.

During the Second world war, the dam Vezins was used to feed the arsenal of Cherbourg as well as the Atlantic Wall. A sabotage destroyed two Transformateur S, which delayed the construction of part of these fortifications.

Nowadays, a base of leisures is installed at the edge of the lake: the base of leisures of Mazure. One practices there fishing, the kayak, the oar, canoeing, etc
